A simple yet great idea, I have downloaded the installer and will put on a Raspberry Pi on monday to try it out.
The part I like is that it is getting students out and trying something different, a little download with a big outcome.
UPDATE: have managed to get this up and going, rather than using code.local I have had to use the IP address of the RPi to be able to access it. Password requires two Capital Letters and lowercase letters.
Interesting concepts are shown on the first screen with an introduction of how to use it.
You need to have it connected to a physical network before you can setup the wifi through the settings console.
More than one user can access the RPi as long as they have the password, but cannot collaboratively change it, you need to save the changes.
An issue: how do you add more than one page to a project? This will also impact on the css link as well.
